A completely collapsed, massive dead star whose gravitational field is so powerful that no radiation can escape from it; because of this property, its existence must be inferred rather than recorded from radiation emissions

A collapsed massive star (or other collapsed body) whose velocity of escape is equal to or greater than the speed of light; thus no radiation can escape from it.

The final stage in the lifecycle of a supermassive star. A black hole is so dense that its gravitational field prevents even photons of light from escaping

An object thought to be the result of a massive star’s implosion in which its gravity has become so dense and strong that it prevents light from escaping.

A region in which matter has collapsed to such an extend that light can no longer escape from it.

A black hole is a region in space where there is so much mass in such a small space that the mass cannot support itself, and collapses to a single point, or singularity. The gravitational pull very close to this point is so strong that not even light can escape if it is within the event horizon of the black hole. Outside of the event horizon, while the black hole would not be directly visible, gravitationally it would be no different than a massive star.

A highly condensed region of matter, with a gravitational attraction so strong that anything that comes too close to it – even light – cannot escape. Black holes can't be seen, but can be detected through the gravitational effects they exert on other objects. Some black holes are the end product for massive stars as they evolve.

(It is not clear exactly what happens to things after they have been 'swallowed'.) Black holes can't be seen, but can be detected through the gravitational effects they exert on other objects.

The dense remains of a massive star, with such a strong gravitational field that light cannot escape from it. The Earth and beyond

A region of spacetime where the warpage of both space and time (gravity) is so intense that nothing—even light— can ever escape. Objects may fall in to the Black Hole, but once they pass the Event Horizon, they can never escape again. Most Black Holes believed to exist are thought to be formed in the collapse of very large stars, or the collision of stars or other Black Holes.

a place where the gravity is so strong that light can't even escape from it. how would you know where to look for it? it can also be interpreted as gateways to an alternative universe.

An object whose gravitational pull inside a certain radius is so strong that nothing, not even light can escape it. A black hole forms when the amount of matter in the core of a star undergoing a supernova is great enough to cause a runaway gravitational collapse.

a body whose escape velocity is greater than the speed of light, causing gravity to pull back toward the body any light it would otherwise emit (see black holes)

A region of space-time that is bended inward due to the extreme force of gravity. It traps anything even light that passes its event horizon.

A black hole is a theoretical construct of the general theory of relativity, where mass is contained in a small enough volume to produce a gravitational field strong enough to prevent the escape of light ("black"), and to produce a (spherical) trap which would ensnare anything, or anyone, unlucky enough to enter ("hole"). A black hole may result when the core of a sufficiently massive star collapses at the end of the star's thermomuclear burning stages (at the end of its normal lifetime). A supermassive black hole is thought to lie at the center of an active galaxy (e.g., radio galaxy, quasar), and many normal galaxies; small mass black holes might have been produced during the Big Bang ("primordial black holes"). Some early attempts to reconcile general relativity (a non-quantum-mechanical theory) with quantum mechanics have suggested that a black hole can slowly "evaporate" --- shrink, while spitting out mass --- over time. Such evaporation would proceed faster as the mass of the black hole became smaller resulting in an energetic burst of output at the end of the process. More.

The leftover core of a super massive star after a supernova. Black holes exert a tremendous gravitational pull. CELSIUS A scale on a thermometer where the interval between the boiling point and the freezing point of water is divided into 100 degrees. Freezing point is represented by 0 degrees and boiling point is represented by 100 degrees. The same scale is also utilized in Centigrade.

An object of finite mass and infinite density, from which light cannot escape.

An object with so much mass concentrated in it, and therefore such a strong gravitational pull that nothing, not even light can escape from it. One way in which black holes are believed to form is when massive stars collapse at the end of their lives.

The thing that big stars become after they die. Black holes have very strong gravity - not even light escapes

a distortion in the fabric of space time which occurs when the density of matter becomes too great and a self-accelerating process warps four-dimensional space time to a point singularity. The singularity is surrounded by an event horizon-a spherical boundary that imprisons all mass and radiation that crosses it. It is called black because it does not allow radiation (light) to escape.

Refers to an opening or window in a room that appears to be empty darkness, especially at night, because there is insufficient illumination at the other side to light up the objects or features framed by the opening.

The ultimate cosmic plughole formed when a high mass supergiant star explodes in a supernova explosion at the end of its life creating a super-dense point in space where nothing can escape the gravitational pull. A star probably has to have a mass of more than 40 solar masses to create a black hole which typically have a mass of about 3 solar masses. Black holes can be detected by the disrupting effects they have on neighbouring stars. The centres of most galaxies including our own are believed to have super-massive black holes which have sucked in thousands of stars.

an extremely compact object, collapsed by gravity which has overcome electric and nuclear forces. It is believed that stars appreciably larger than the Sun, once they have exhausted all their nuclear fuel, collapse to form black holes: they are "black" because no light escapes their intense gravity. Material attracted to a black hole, though, gains enormous energy and can radiate part of it before being swallowed up. Some astronomers believe that enormously massive black holes exist in the center of our galaxy and of other galaxies.

The area around a collapsed star that light cannot escape. Also, what happens to the careers of former child stars like Corey Feldman

When a very massive star goes supernova, the resulting energy can squeeze the star's mass into a very small but super massive object know as a "black hole". A black hole has so much gravity that not even light can escape from it.

Extremely dense remnant of a very massive star. Its gravitational attraction is so strong that light cannot escape from it.

If the mass of a dying star is greater than about 2 to 3 solar masses then it cannot form a neutron star. This is because the neutron degeneracy pressure will no longer support the star at this mass. The star then completely collapses to a singularity. The mass is concentrated into an infinitesimally small volume and this distorts the space-time continuum to such an extent that nothing can escape from the black hole.

A collapsed star that is so dense that not even light can escape its gravitational pull, hence the term Black Hole, it cannot be seen

A region of space that nothing, not even light, can escape from.

A region of space-time formed by the collapse of a massive object, such as a star. A black hole is coined "black" because nothing, not even light, can escape its grasp.

A collapsed massive star; so dense that not even light can escape the pull of its gravity

a region in space where gravity is so strong that not even light can escape from it. Black holes in our galaxy are thought to be formed when stars more than ten times as massive as our Sun end their lives in a supernova explosion. There is also evidence indicating that supermassive black holes (more massive than ten billion Suns) exist in the centers of some galaxies.

an object whose gravity is so strong that not even light can escape from it.

A region of outerspace where the gravitational field is so intense that nothing, including light, can escape. The point of no return, the edge of the black hole, is often called the event horizon. A block hole is formed when a massive star burns out its nuclear fuel and collapses under its own weight. If the star is large enough, it will form a black hole. Some stars collapse to form a Naked Singularity. Black holes tend to stretch and tear local space-time, to such an extent that block holes are often gateways into universes of anti-matter and superspace.

The collapsed core of a massive star. Stars that are very massive will collapse under their own gravity when their fuel is exhausted. The collapse continues until all matter is crushed out of existence into what is known as a singularity. The gravitational pull is so strong that not even light can escape.

The leftover core of a super massive star after a supernova. Black holes exert a tremendous gravitational pull. CHARGED PARTICLES electrons, protons, ions.

caused by the death of an extremely large star, black holes have gravitational fields strong enough to trap light. Black holes consist of a singularity, the center where all the mass resides, and an event horizon, a black disk encircling the singularity and the point at which light can no longer escape the gravitational forces of the black hole

a region of space where gravity is so powerful that not even light can escape.

An object so dense that light cannot escape from it.

An object that is so compact (in other words, has enough mass in a small enough volume) that its gravitational force is strong enough to prevent light or anything else from escaping. What is a black hole

The remains of a massive star that has burned out its nuclear fuel and collapsed under tremendous gravitational force into a single point of infinite mass and gravity.

A mass that has collapsed to such a small volume that its gravity prevents the escape of all radiation; also, the volume of space from which the radiation may not escape.

black hole is a massive object (or region) in space that is so dense that within a certain radius (the Schwarzschild radius, which determines the event horizon), its gravitational field does not let anything escape from it, not even light. It is thought that giant stars (those with a mass over 3 times the mass of the Sun) will evolve into red supergiants, then supernova , and then black holes. It is thought that the typical black holes has a mass of roughly 10 times that of the Sun, but the range must be huge. For a typical black hole with a mass 10 times that of the Sun, the Schwarzschild radius would be roughly 18.6 miles (30 km). The phrase 'black hole' was coined by the physicist John Archibald Wheeler; before Wheeler, black holes were called 'frozen stars.' Astronomers think that there may be a black hole at the center of each galaxy.

An object so small yet so massive that escape speed exceeds the speed of light. General relativity predicts the possibility of black holes, and modern astrophysics has essentially confirmed their existence.

An object with such high gravity that not even light can escape. These may be formed when the most massive of stars die, and their cores collapse into a superdense mass.

A region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull.

black holes form the stellar core from the remainder of the star that exploded as supernovae. If the core is greater than 3 solar masses then the core will contract to become a back hole. Black hole are described by there considerably strong gravity, it is so powerful that even light cannot escape. as a result of this, black holes are invisible. But they can be detected if they have a companion star. The gravity from the black hole pulls the gas from the star forming an accretion disc that circles the the black hole at great speeds, heating up and emmiting radiation. Soon after the matter from the star spirals to cross the event horizon therefore dissappearing from the visible Universe.

A singularity in space-time from which light and matter cannot escape; an object so massive that the escape velocity is greater than the speed of light.

the result of the gravitational collapse of a massive star. Its gravitational attraction acts as a kind of "hole" which swallows every celestial body that comes near to it; it is so strong that not even light can escape, hence its name.

A region of space resulting from the collapse of a star with an extremely high gravitational field.

mass that has collapsed to such a degree that the escape velocity from its surface is greater than the speed of light, so that light is trapped by the intense gravitational field.

An object whose gravity is so strong that the escape velocity exceeds the speed of light.

A massive system so centrally condensed that its force of gravity prevents everything within it, including light, from escaping.

A localised region of space from which not even light can escape, due to a super massive star collapsing in on itself. This is because the gravitational field of a black hole is so strong that the escape velocity is greater than the speed of light. Astronomers believe that the location of large black holes can be observed because of radiation emitted from the accretion disc as matter is pulled into the black hole. The event horizon marks the outer limits of these objects.

A black hole is an object predicted by general relativity,The Singularities of Gravitational Collapse and Cosmology. S. W. Hawking, R.

Black Hole is a solitaire card game that is akin to Golf and Tri Peaks, but its tableau is somewhat like that of La Belle Lucie. Invented by David Parlett, this game's objective is to compress the entire deck into one foundation.

Black Hole is a graphic novel written and illustrated by Charles Burns. It was originally published as a 12-issue comic book series between 1995 and 2005 by Kitchen Sink Press and Fantagraphics, and then released in a compiled hardcover edition by Pantheon Books in 2005.

Black Hole was a pinball game released in 1981 by Gottlieb. It is notable for having two playfields: one on top with a conventional slope, and one mounted underneath sloping away from the player. The lower playfield is viewed through a window in the upper playfield.

In networking, black holes refer to places in the network where incoming traffic is silently discarded (or "dropped"), without informing the source that the data did not reach its intended recipient.
